It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-87677 in the wild and no public exploit code.\n\nAffected product: Broadcom Fabric Operating System. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-87677/ (Markdown: https://insights.sbomify.com/CVE-2026-87677/index.md)","id":"CVE-2026-87677","markdown":"https://insights.sbomify.com/CVE-2026-87677/index.md","name":"CVE-2026-87677","record":{"aliases":["GHSA-fw7w-5rwg-xvrv"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Brocade Fabric OS","requires_auth":"high_privilege","summary":"An attacker with admin privileges can execute arbitrary commands via malformed account names during account deletion in Brocade Fabric OS.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"brocade","cpe":[{"product":"fabric_operating_system","vendor":"broadcom"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:H/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"An OS command injection vulnerability exists in the account management subsystem of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1.
